IMPROVEMENT IN HARV ESTERS.

Specification forming part of Letters Patent No. 35,970, dated July 22, 1862.

To all whom it may cozzceriz:

Be it known that I, R. M. DAVIS, of Eaton, in the county of Madison and State of New York, have invented certain new and useful Improvements in Harvesting-ll/Iaehines; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, making a part of this specification, in which Figure 1 is a top view. Fig. 2 is a side view. Fig. 3 is a side view of outer shoe and trackclearer. Fig. 4 represents the knife and the mode of connecting it with the pitman; also the crank and the mode of connecting the pit-' man therewith. Fig. 5 is a side View of the tongue and drivers seat; also, a shaft with a pulley connected therewith. The red line reprents the tongue when turned around so as to draw the machine in an opposite direction. Said tongue is also represented in like manner in Fig. 1. Fig. 6 is a top View of the arch for connecting the finger-bar to the frame. Fig. 7 is a side view of the inner shoe.

Previous to the herein-described invention no suitable mechanical invention had to my knowledge ever been essayed for turning over the finger-bar of "a harvesting-machine without disconnecting the knife from the pitman; nor had there ever been any arrangement of mechanism for turning over the track-clearer in an opposite direction from that which the finger-bar is being turned and operating at the same time; nor has there ever been any mechanical device, so combined with a fingerbar and with the main frame as that by turning the main frame half round the finger-bar will be turned over, so as to enable the ma chine to be drawn in an opposite direction and work equally well whichever end goes foremost; nor has there ever been any device by which the finger-bar could be turned over by turning the tongue around horizontally and independent of the main frame of the machine with or without the drivers seat located on the rear end of said tongue. The mechanical arrangement for producing the aforesaid sev eral results is equally and alike applicable to a machine which is provided with a fingerbar that may be turned horizontally around, as upon a machine which is provided with a finger-bar that remains at all times on the.

same side of the machine. In the latter case the device which I am about to describe can be used to much better advantage on a machine which has the finger-bar located in line, or nearly so, with the center of the main frame of the machine. 011 such a machine the team will be about the same distance from the finger-bar whichever end of the main frame goes foremost.

To enable others skilled in the art to make and use this invention, I will proceed to de* scribe its construction and operation.

A represents the main frame of a harvesting-machine, which is supported on the wheels B B, said wheels being also the driving-wheels. To the rear of said frame the arch or armpiece 0, to which the fingerbar is attached, is pivoted in such a manner that the fingerbar and arm-piece turn horizontally around on a pivot at F.

The finger-bar is connected to the inner shoe by a round journal. (Shown at H.) This j our nal should have a'good degree of strength to prevent torsion or twisting. The innerend of said journal, as shown at z, is connected to an arm, J which is provided with what I term a balljoint! Said arm has also a similar joint at the opposite end, which is connected to gearing, which is'in turn connected to the arm or arch.

In order to allow the fingerbar to rise and fall and accommodate itself to theinequalities of the ground when mowing, or to pass over obstructions and be held up at any desired elevation, I make a joint in the arch, as shown at P, Fig. 1, and an extension-joint in the arm, as shown at Q. By this arrangement the aforesaid result is accomplished without deranging any of the parts. .By this jointed connection with the finger-bar and the gearing referred to the finger-bar is turned over, so as to cut when the machine is moved forward, it matters not on which side of the main framethe finger-bar projects. I also employ the tongue or draft-pole to turn over the finger-bar, which is connected to an upright. (Marked N.) 011 the lower end of said upright is a grooved pulley which is in a line horizontally, or nearly so, with another pulley. (Marked M.) A band, endless chain, or any well-known mechanism may be employed to connect them. By this arrangement the finger-bar will be turned over by reversing the draft-pole. The reversi-. ble draft-pole is more particularly adapted to harvesters that have the finger-bar located on or near the center of the main frame, as hereinbefore referred to. The drivers seat is located on the rear end of the draft-pole, as shown at K, and is turned with the tongue. By this mode of connecting the pitman to the crank-head S and the knife-bar 19, as shown in Fig. 4, it will be seen it is of such character as to enable the finger-bar to turn over, and also around from one side of the machine to the other or opposite side, without disconnecting the pitman at either end.

The track-clearer and outer shoe is combined with the finger-bar in such a manner that by rotating the lower pinion, (marked U,) which meshes into the upper pinion, (marked V,) the track-clearer is turned in an opposite direction from that in which the finger-bar is rotated. I

The outer shoe (shown in Fig. 3) is constructed with a double point, which separates the grain or grass when the machine is drawn in either direction.

\Vhat I claim as new, and desire to secure by Letters Patent. is

1. A finger-bar so combined with the frame of the harvester and the mechanism by which the cutters are vibrated that it may at pleasure be turned over, so that the machine 'may be drawn in either direction and perform the same duty, substantially as described.

2. Combining with the outer end of a fingerbar of a harvester a track-clearer for the purpose of sweeping the out grain or grass inward as it falls over said finger -bar by mechanism, substantially such as represented and described, whereby the track-clearer is made to always project rearward or behind the finger-bar and at an acute angle therewith, its movements being governed by the rotation of the finger-bar, substantially as described.

3. Combining with theinner end of the fingerbar an operative arm, and by mechanism, substantially such as described, the opposite end of said arm with the main frame and draft pole, which is pivoted to the main body of the machine, whereby the finger-bar may be inverted either by turning the main body of the machine or without changing the main body of the machine, substantially as described.

4. Combining with the inner end of the finger-bar an operative arm provided with an. extension-joint, Q, and the ball-joints i 'u', or their equivalents, whereby the finger-bar may be supported at any desired elevation, and the rotation thereof be accomplished by means substantially such as described.

5. The combination of the pitman or connecting-rod with the crank-head at one end and to the knife-bar at' the opposite end, so that the cutter-bar may be inverted without disconnecting the pitman, substantially as shown.

6. The combination of the pitman or connecting rod with the knife-bar E and fingerbar D, whereby they may both be rotated in the manner substantially as represented and described, and for the purposes specified.
